Convex Lens Ray Diagram Table. When a ray strikes concave or convex lenses obliquely at its pole it continues to follow its path. Image formation in a convex lens can be explained with the help of three principal rays shown in the figure.
Give reason in support of your answer. How did you arrive at this conclusion. For a concave lens there are only 2 casesthey areobject is placed at infinityobject is placed between infinity and optical centercase 1 object is placed at infinityin this case object is kept far away from mirror almost at infinite distance so we draw rays parallel to principal axissince ray pa.
The ray parallel to the principal axis passes through the focal point after refraction by the lens.
B write the serial number of that observation which is not correct. The ray passing through optical centre passes straight through the lens and remains undeviated. If those surfaces are bent outwards the lens is called a biconvex lens or simply convex lens. Ray diagrams help us trace the path of the light for the person to view a point on the image of an object.
